The present invention relates to a machine or apparatus for conditioning materials for use and relates more specifically to a machine particularly well adapted for reconditioning prepared paint and other liquids of such ingredients as will separate or deposit when left in a condition at rest.

Prepared paint as now generally sold in closed containers such as cans, buckets and the .10 like of various sizes, require thorough stirring of the paint in order to recondition the paint for use. Owin to the fact that in many instances, long periods of time elapse between the time the paint is made and when ultimate- .1 ly opened for use, the pigment settles the oil or other liquid of the mixture and requires considerable time and efi'ort upon the part of the consumer to recondition the paint for use. 1

It is therefore a primary object of the present invention to provide a paint condi tionin g machine whereby prepared paint may be reconditioned for use without requiring the container to be opened.

A further object of the invention is to.pro vide a power operated machine, whereby paint, sold in containers of various sizes, may be quickly and efliciently prepared for use.

A further object is to rovide a paint conditioning machine whereby containers of prepared paint may be oscillated in a manner for thoroughly mixing the paint before opening the container.

A further object resides in the novel arrangement whereby one or more containers of diiferent sizes may be operated upon at the same time and without damage to the containers.

A still further object is to provide a machine of this character which will be extremely. compact and embodying features of construction whereby the paint may be violentlv agitated without causing excessive vibration to the machine.

Other objects and advantages of the invention willbe apparent during the course of the following detailed description, taken in connection with the accompanying drawings forming a part of this specification-ar d 9 in which drawings:

ing sleeves 13 which project outwar Figure 1 is a view in side elevation of the machine and showing an electric motor connected for operating the machine.

Figure 2 is a top plan view of the machine and showing a holder applied toone end of the rock shaft.

Figure 3 is a vertical section-on the line 33 of Figure 4. Figure 4 is a vertical section on the line H of Figure 3. o Figure 5 is a vertical section similar to Figure 3 butshowin'g the rock shaft in an opposite limit of movement from that shown in Figure 3.

Figure 6 is a perspective view of one of the chucks for detachably receiving the hold- Figure 7 is a fragmentaryside view of one of the holders and showing the coupling plate for releasably connecting the holders to the chucks.

In the drawings, and wherein similar reference characters designate correspondin parts thruout the several views the improve machine comprises a casing or housing A embodying parallel side walls 5 and 6, upwardly converging end. walls 7 and 8 and a bottom wall .9 providing a'closed chamber for enclosing the oscillatin mechanism B. The lower edges of the si e walls 5 and-"6 may conform to the shape of the bottom wall 9 which as clearly shown in Figures 3 and 4 is downwardly curved from the lower portion of the end wall 7 and extends upwardly at an angle to about midway the height 01 the end wall 8. The upper end of the casing may be closed b a removable cover plate 10. and the end wal 7 may be provided adj qlcent a removable plate 11.. The lower ends of the end walls 7 and 8 may be outturned to provide suitable base. flanges thru which fastening elements may be extended for mount- A suitable reinforcin web as at 12 may extend-beneath the centra portion of the bottom wall 9' and connect the lower portions of the end walls 7 and 8. The side walls 5 and 6 are provided adjacent their upper ends with axially aligninglbegi; y

yond the walls andeach of which is provided with a suitable bushing 14. The side wall 5 is formed with an outwardly oliset portion bushing 19.

The oscillating mechanism B embodies a crank shaft 20 journaled at its ends in the bearings 15 and 19 and provided intermediate its ends with a counter-balanced crank 21 arranged between the inner ends of the I bearin The projecting end of the shaft 20 which extends thru the'bearing 19 has.

mounted thereon a suitable belt wheel 22 whlch may either be of the grooved type as shown for receiving a V belt or may have a fiat belt base for receiving a flat belt.

Oscillatively journaled in the bearings 14 is a rock shaft 23havingsplined ends 24 projecting beyond the bearing sleeves 13.,

This rock shaft 23 as will be observed is mounted in parallel relation to the crank shaft 20 in slightly spaced relation above the periphery of the belt wheel 22.

Keyed at one end upon the rock shaft 23 between the bearings 14 is a rocker arm 25 having a forked end 26. Connecting "the crank pin 21' of the crank 21 with th'el' forked end 26 of the rocker arm 25 is a connecting rod 28 for imparting a rocking movement to, the shaft 23 upon rotation ofthe crank shaft 20.

Secured to each end of the rock shaft 23 is a chuck 30 as shown in detail in Figure 6 and these chucks each embody a tubular hub portion 31 which is internally splined for receiving the splined rock shaft ends 24 whereby the chucks are held for rocking movement with the shaft 23. Carried by the outer end of each hub 31 is a chuck plate 32 having its side edges beveled toward the hub 31 as at 33 with the upper portion of one beveled side edge tapered as at 34. The hubs 31 roject at a right angle from the plate 32 and are arranged midway between the ends of the plate.

Each of the chucks 30 is adapted to removably support a holder C adapted to receive the cans of paint to be mixed by the machine. The holders C include receptacles of cylindrical shape embodying a fixed semicircular section 35 and a hinged section 36 hingedly connected along one side edge to the section 35 by suitable hinges 37. Carried by the free edge of the hinged section 36 is a pair of snap fasteners 38 each embodying a locking lever 39 for engagement withsuitable hooks 40 carried by the section 36. Provided at the lower end of the holder section 35 is a disc-shaped bottom wall 41. Arranged at the upper end of the section 35 isa substantially semi-circular shaped top plate'42 carrying a clamping screw 43 adapted to be turned down into engagement with the top of the paint can arranged in the receptacle.

Secured in any preferred manner along the holder section 35 is a mounting plate 45 provided along its side edges with three coupling lugs 46 for engagement with the beveled side edges of the chuck plate 32. These coupling .and so oscillate the holders as to thoroughly mix the material in the containers clamped in the holders. It may here be well to note that the containers will be held in a substantially vertical position in the holder-s and willbe oscillated'about a horizontal axis at a right angle to the longitudinal or vertical axis of the container with the axis of oscilla- V tion substantially midway the height of the container. While only one of the holders C has been shown applied to one of the quick change chucks 30, the chucks are each of like construction permitting a holder to be applied to each end of the rock shaft 23 when such is'desired. The driving connection between the shaft 20 and shaft 23 is preferably such as to cause the chucks to be rapidly oscillated thru an angle of 60 or less and thus the containers are held in a substantially vertical position while being oscillated.

The casing A provides a closed chamber in which lubricant may be retained for thoroughly oiling the oscillating mechanism B. It will also be noted that the specific formation of the casing provides an arrangement whereby relatively long bearings are provided for each of the shafts 20 and 23 and allows for the belt wheel 22 to be disposed between one of the chucks and the casing side wall 6 so that the belt 52 does not interfere with ready placing and removal of holders on the chucks.

From the foregoing it will be seen that a device has been provided whereby prepared paint as sold in containers may be quickly and easily reconditioned for use without opening the containers. It will-also be apparent that a novel arrangement has been disclosed whereby containers of various sizes may be oscillated in a manner for violently agitating the contents thereof. It will further be noted that a novel arrangement has been shown whereby the holders are rigidly held in a releasable position upon the chucks in a manner whereby the containers are held in a substantially vertical position and oscillated about an axis substantially midway the height of the container.-

Changes in detail may be made to the form of invention herein shown and described, without departing from the spirit of the invention or the scope of the following claims.
